A) \[+\]and\[-,\]2 and 3
B) \[+\]and\[-,\]2 and 5
C) \[+\]and\[-,\]3 and 5
D) None of these
Correct Answer: A
Solution :
By making the interchanges given in (a), we get the equation as \[2-5+3=0\]or \[0=0\] which is true. By making the interchanges given in (b), we get the equation as \[3-2+5=0\]or \[6=0,\]which is false. By making the interchanges given in (c), we get the equation as \[5-3+2=4\]or \[4=0\] which is not true. So, the answer is (a).
